Ignorance and fear of the disease can disrupt families and communities and may even【C3】______political relations between nations.
     Because AIDS is a worldwide epidemic(传染病，流行病), nothing【C4】______than a worldwide effort can control and perhaps some day wipe the disease.

【C7】
选项 A、how
B、what
C、whether
D、that
答案B
解析 需要what在这里作定语：告诉人们应该采取什么样的措施以防感染。为何不能用about呢?的确，tell．．．about也是个固定词组，原因是用了about，意义还是没有表达出来，语法上也存在缺陷。如果后面是(about)the right actions how．．，那就可以了。
